Jan 31, 2020· How Coal Power Works. Coal is a combustible sedimentary rocklike material made mostly of carbon and hydrocarbons. Like fossils, each piece of coal began as living plants or animals and was transformed by natural forces. Coal forms when peat bogs are covered by layers of rock and dirt, resulting in tremendous pressure and heat.
The map shows coal capacity, whereas electricity generation and CO2 emissions depend on a range of other factors. Most important is how often coal plants run – their load factor. Global average loads started falling in 2007 and coal power CO2 has levelled off since 2014. More on this below.
